Don't use nqp::iterator iterating over mutable QuantHashes

This used to depends on R:I.ITERATIONSET2LISTITER that would create a native string array of the keys of a QuantHash and then return an iterator for it. Changed it to return the native string array instead and adapted the users of it. Also changed the name of the internal method to a more descriptive: IterationSet2keys
Also other assorted cleanup in this area to make better readable code.		 13:12
lizmat I think this has now eliminated the use of nqp::iterator on lists in the core

Fix a shaped array performance problem

When we want to turn a native array into a shaped native array, we steal the meta-object and re-use it on a new type with the multi-dim array representation. While that preserves the type behavior (aside from representation), there's a new STable, which lacks the various caches. Having those attached means there's now no non-cached type check or method lookup MOP queries when we work with shaped native arrays, which was the cause of the slow performance compared to non-shaped native arrays.		 17:56

Sort all entries alphabetically for easier lookup

Also add a "sort-ops" script that will make sure that all sections and all ops in "ops.markdown" are in alphabetical order, except for the "Miscellaneous sections" that will always be listed last.
Add a new section is easy: add the section at the end, move any ops that you want in there in that section, and run the "sort-ops" script again. It will automatically add the new section to the table of contents at the beginning.		 20:01
cognominal Hi. Building nqp on Apple Silicon fails except when JIT_DISABLE is set to 1. Indeed once the build is done and I unset JIT_DISABLE. lldb says me moar crashes on jit_enter 20:05
Probably the fix is trivial, but I don't know where the config decide to generate code for jitting knowing there is none implemented for ARN64 20:07
lizmat cognominal: probably better asked on #moarvm :-)
or as an issue on MoarVM :-)
cognominal Yes I will write an issue and dig to find a fix 20:09
